Details

Demand for electricity in York Region has grown beyond the capacity of existing electricity infrastructure serving the Region. The Board has directed the utilities serving York Region – Hydro One Networks Inc., Newmarket Hydro and PowerStream Inc. – (the “York Region Utilities”) to identify the optimal transmission and/or distribution infrastructure investment to serve York Region. At the same time, the Ontario Power Authority (the “OPA”) led public meetings and established working groups to engage local stakeholders in the OPA’s identification of solutions to the York Region supply issue.

On June 29, 2005 the York Region Utilities advised the Board in writing that the preferred solution involves the installation of a new transformer station at the Holland Junction transmission point in the Township of King with associated distribution feeder lines (the “Holland Junction Proposal”).

On September 30, 2005, the OPA’s evidence indicated that the preferred option, in the immediate term, is the Holland Junction Proposal. The OPA also stated that they will be pursuing opportunities for conservation and demand management in York Region.
